The SAHBA home show is a convention that takes place in Tucson twice a year, once in spring and once in fall, featuring products and vendors to help improve your home, patio, or pool. The cost for admission does seem a bit high for something of this nature at $ 8/person, but there are on-demand coupons printable online for $ 2 off admission. It seems odd to me that they’d even have a coupon for a convention, why not just make the admission price $ 6/person? The ballroom and convention floor were packed with vendors and with people, even early in the morning. So a good strategy might be to look over the map online first and highlight what vendors you’d like to see. Some personal highlights from the 2012 Spring show include: –Canyon Pondscapes, a great way to use rainwater harvesting not only for watering your garden but also adding in a water feature(RainXchanage). –The Solar Store, a solar installer that has been in business for 15 years and is very knowledgeable about the product. — EMMCo, HVAC contractors who also specialize in tankless water heaters.
